Subject [jira] Commented: (MAHOUT-588) Benchmark Mahout's clustering performance on EC2 and publish the results
Date Tue, 01 Feb 2011 17:18:29 GMT


Timothy Potter commented on MAHOUT-588:

Hi Szymon,

I'd like to use the vectors you created with the more sophisticated analzyer. Can you post
the tfidf-vectors directory from your HDFS to Grant's S3 bucket, such as: s3n://asf-mail-archives/mahout-0.4/tfidf-vectors

Best way would be to use distcp out of Hadoop using:

hadoop distcp HDFS_PATH/tfidf-vectors s3n://asf-mail-archives/mahout-0.4/

You'll also need to setup your s3n access key and secret key in core-site.xml, such as:

 I've asked the two doing the project to do all the work in the open here.  The goal is to
use a publicly reusable dataset (for now, the ASF mail archives, assuming it is big enough)
and run on EC2 and make all resources available so others can reproduce/improve.
> I'd like to add the setup code to utils (although it could possibly be done as a Vectorizer)
and the publication of the results will be put up on the Wiki as well as in the book.  This
issue is to track the patches, etc.
